Duct Fiber Optic Cable

Description
Duct laying fiber optic cables are a common communication fiber optic cable used primarily in outdoor applications. We provide GYXTW duct fiber optic cables to our customers, and the production process is as follows. We first insert the 250um optic fiber into a loose tube made of a high modulus material and then fill the loose tube with a waterproof compound. The loose tube is then wrapped with PSP, and a water blocking material is inserted between the loose tube and PSP in order to ensure the tube is tightly coated and waterproof. Finally, two steel wires are placed parallel to each side of the PSP jacket, then squeezed in a PE sheath.

Features The fiber optic cable features a high tensile strength, and is used for self-supporting aerial laying to decrease installation costs. The loose tube material features an excellent hydrolysis resistance and higher strength. The special factice filled in the cable protects the fiber. The duct fiber optic cable has a great stress tolerance and flexibility. The PSP improves the moisture proof performance. Two parallel steel wires ensure the tensile strength of the fiber optic cable. The duct fiber optic cable is light weight and easy to install.
